Abstract: The paper introduces the system structure and work principle of the monitoring and control system for automated multi-layer garage. It also introduces emphatically how to realize information interchange between the applications by multi-applications applied together based on network data transfers and DDE protocol in the monitoring system for automated multi-layer garage. By this way, it can overcome the shortage in which the Visual Basic6.0 application procedure handles the multi-threading, and makes automated multi-layer garage fast controlled and managed.
